FaceAntiSpoofing : A Machine Learning Model to Determine If a Face is Real
This is an introduction to「FaceAntiSpoofing」, a machine learning model that can be used with ailia SDK. You can easily use this model to create AI applications using ailia SDK as well as many other ready-to-use ailia MODELS.
Overview
FaceAntiSpoofing is a machine learning model that determines whether a face in a picture is real (an actual person being photographed) or fake (printed on a sheet of paper). It can be used for identity verification (Know Your Customer, or KYC for short) and other purposes.

Architecture
FaceAntiSpoofing is based on MobileNetV3 and was trained on the CelebA-Spoof dataset.

CelebA-Spoof contains images of faces printed on paper or displayed on a PC, tablet, or cell phone.

It also contains variants of the same picture under different angles and shapes.

Usage
FaceAntiSpoofing can be used with ailia SDK using the following command. By appending the --detection option, the faces are detected in the input image and labelled as real or fake.
$ python3 face-anti-spoofing.py --input input.jpg --detection
